9902.08.85 - 2,2'-(Vinylenedi-p-phenylene)bisbenzoxazole (CAS No. 1533-45-5) (provided for in subheading 3204.20.80)

This HTS category, 9902.08.85, specifically covers the chemical compound 2,2'-(Vinylenedi-p-phenylene)bisbenzoxazole, identified by CAS No. 1533-45-5. This substance is a type of optical brightening agent, often used to enhance the appearance of textiles, plastics, and paper by absorbing ultraviolet light and re-emitting it as blue light, making materials appear whiter and brighter. Its classification under Chapter 99 signifies a temporary modification or special provision related to its importation.

As a leaf node within the HTS structure, this specific code does not have direct subcategories. Its distinction from sibling categories at the same level lies in its precise chemical identity and its application as a specialized optical brightener. Unlike broader categories for general chemicals or other types of dyes and pigments, 9902.08.85 is reserved for this particular benzoxazole derivative, indicating a unique treatment or monitoring for customs purposes. The parenthetical reference to subheading 3204.20.80 further clarifies that while its primary commercial use might place it within the scope of synthetic organic coloring matter and preparations thereof, this specific 9900 series code applies a temporary or specific duty rate or restriction.
